Simultaneous generation of high power, ultrafast 1D and 2D Airy beams and their frequency doubling characteristics
Raghwinder S. Grewal, Anirban Ghosh, G. K. Samanta
We report on a simple experimental scheme based on a pair of cylindrical lenses (convex and concave) of same focal length and common optical elements producing high power optical b…
Controlling the biphoton orbital angular momentum eigenmodes using asymmetric pump vortex beam
M. V. Jabir, Ali Anwar, G. K. Samanta
We report on controlling the bi-photon orbital angular momentum (OAM) eigenmodes in the spontaneous parametric down conversion process by simply adjusting the asymmetry of the pump…
High-power, continuous-wave, tunable mid-IR, higher-order vortex beam optical parametric oscillator
A. Aadhi, Varun Sharma, G. K. Samanta
We report on a novel experimental scheme to generate continuous-wave (cw), high power, and higher-order optical vortices tunable across mid-IR wavelength range. Using cw, two-cryst…
Controlled generation, manipulation and frequency conversion of broadband orbital angular momentum spectrum of asymmetric optical vortex beams
Sabir Ul Alam, A. Srinivasa Rao, Anirban Ghosh +2
We report on generation and control of tunable, broad orbital angular momentum (OAM) spectrum of a vortex beam. Using two spiral phase plates (SPPs), we have converted the Gaussian…
